This invention relates to "dental scrubbers, particularly detachablefillers for handles.

Referring to the drawings:

Fig. 1V is a side elevation of an embodiment of the invention in a toothbrush or scrubber;

Fig. 2 is a plan view of the brush handle of Fig. l; l

Fig. 3 is an end elevation of the scrubber of Fig. l, with the fillerbroken away adjacent its mounting;

Fig. 4 is a section on the line lV-IV', Fig. 2, showing the fill-erassembled with the hann dle; Fig. 5 is a plan view of the filler;

Fig. 6 is an end elevation of the filler of Fig. 5;

Fig. 7 is a side elevation of the filler of Fig. 5;

8 is a fragmentary view showing the coaction of t-he prongs of thescrubber or filler for entering the recesses ybetween the teeth of theuser of this scrubber; and

Fig. 9 is anenlarged perspective view of one of the prongs.

Handle 1 is shown as having near one end thereof an elongated slot 2terminating in seats 3. Yieldable clip 4. of general U-form, hasoutwardly extending termini 5 which, passing through openings 6, coactwith the pair of seats 3, while between these openings 6 intermediateportion 7 of rubber filler 8 is i embraced. to assemble such flexiblerubber filler detachably with the handle l. This action of the clip 4 indrawing the interme# diate portion 7 of the filler 8 toward the slot 2as an intermediate seat inthe handle flexes wing portions of the iiller8 causing cylindrical prongs 9 of such filler to be inclined toward eachother, the outermost prongs 9 bef ing longer than those nearer the seat.These prongs have cylindrical base or body portions and upwardlyterminate in oppositely arcuate sides 10 which inerg-e toward each otherto edge 11 and provide vwedge faces or arcuate seats adjacent thetermini for the prongs. These scrubber prongs 9 are of appioxiinateuniform flexibility in the cylindrical portion thereof, while the doublearcuate wedge .portion approximates -a feather edge'of considerableflexibility at its tip with a degree of strengthened iiexibility towardthe cylindrical portion 9. These wedge port-ions .inl the rows of theprongs are disposed to align transversely of the handle so that as thisscrubber is inserted-in the mouth, oscillation of the scrubber byrocking the handle on its lengthwise axis will allow these wedges tomove up and down between the teeth and thus Y serve as'eifective agentsfor clearing the teeth `of tartar, as well as food particles or foreignThe action of the prongs when the v matter. handle is reciprocatedlengthwise is an effective scrubbing action or polisher for the teeth,and when this flexible prong structure is made of rubber, the action isreallv a polishing and mild scrubbing action without tendency tolacerate the gums. Y

The filler is one which may be readily assembled in the handlestructure, and accordingly with a'handle supplied, there may lbereplacements with fillers of varying sizes, or

when damaged. replacement with a completeV filler. Thesefillers aresanitary, as well as the brush as a unit, and are susceptiblejof rea-dycleansing.

The filler is quickly attached to the handle v by placing the portion ofthe filler over'tlie` slot 2 with the filler openings 6 near t-her slotterminals. One terminal 5 of the clip 4 is then thrust through theopenings 6 of the filler body to have one of its termini enter a seat'and the remote terminus offset sprung into the other seat 3 due to theflexibility of both the clip and the filler.

The eflicient mode for cleansing teeth is b v rubbing the teethlengthwise orv bv up and down motion so that the brush prongs orbristles may enter between the teeth and foreign matter be engaged andbrushed lengthwise therefrom. To this end the concave finforniing edgesll of the prongs Q'are so disposed as to present such edges in adirection to enter effectively between the teeth.

What is claimed .and it is desired to .secure by United States LettersPatent is:

l. A tooth scrubber comprising a base. and

a plurality of flexible prongs rising there-l from, each prong having acylindrical body portion terminating at its free end in an edge, saidprongs each having concave seats one on each side of said edge merginginto said cyl lindrical portion.

2. A tooth scrubber comprising a handle with a slot, a seat in each endof the slot, a 1

flexible clip adaptedto engage the seats, and to secure a flexible brushhead between. said clip and thesides of the slot.
